Police shot dead 13 attackers in China's restive Xinjiang region after they rammed a car into a police station and detonated explosives, the official Xinhua news agency reported on Saturday, in the latest of a series of attacks to worry Beijing.
Xinjiang is the traditional home of Muslim Uighurs who speak a Turkic language, and China has blamed previous attacks on Islamist separatists it says seek to establish an independent state there called East Turkestan.
Three police officers were "lightly wounded" in the attack on Saturday morning, but there were no casualties among the public, the news agency said citing the local government.
"The gangsters drove a vehicle to ram the building of the public security bureau of Yecheng County in southern Xinjiang and set off explosives," it said.

In 2012, seven attackers were shot dead after killing 13 people in a knife attack in Yecheng, also known by its Uighur name of Kargilik, a remote town on the road leading to China's mountainous border with Pakistan.
China has been on edge since a suicide bombing last month killed 39 people at a market in Xinjiang's regional capital Urumqi. In March, 29 people were stabbed to death at a train station in the southwestern city of Kunming.
The rise in violence has prompted a crackdown on violent crime. Authorities in Xinjiang have arrested or tried dozens of suspects in recent weeks for spreading extremist propaganda, possessing banned weapons and other crimes.
